exec fail(pvwattsv5): first two header lines must have same number of columns time -1

Hi,

I have downloaded weather data file from developer.nrel.gov/api/solar/nsrdb_data_query.json by specifying api key and address.

Now, when I try to pass this weather file as is to SSC, it complains

exec fail(pvwattsv5): first two header lines must have same number of columns time -1

I checked the file (attached below) and ensured that first two row indeed have same columns. Can someone please help? I am using sam-sdk-2017-1-17-r2 on Mac.

*** UPDATE ****
Using SAM tool (under Macros->Solar Resource File Generator), it also says "No issue detected in weather file".

Hello,

Please look carefully at Row 1. It appears to have some extra columns that you may have included by accident:

Source,Location ID,City,State,Country,Latitude,Longitude,Time Zone,Elevation,Local Time Zone,Dew Point Units,DHI Units,DNI Units,GHI Units,Temperature Units,Pressure Units,Wind Direction Units,Wind Speed,Version

Best regards,
Paul.
